things weren't quite pauling together. then we came to the first big drop. as i crested the top of the water fall, i could look down and it just looked like this bottomless pit of churning water. i couldn't see a clean outflow or clean exit. i hit the bottom of the water fall and the front end of the boat and i were immediately and completely emerges in 8 or 10 feet of water. i started to do the things that would free me from the boat. but the force of the current had my body absolutely pressed to the front deck of the boat. >> did you have any sense while this was happening where your friends were, what they were trying to do. did they know where you were? >> neither the boat nor i were visible from the surface. and at that point in time, they started their watch. time is very important because it determines whether you are trying to rescue someone or whether you are really just trying to recover the body. >> they had a tough time reaching you. >> because they kept failing. their sense of really of panic kept raising. >> did you think you were going to die
